COOKING AND HEATING STOVE.

SPECIFICATION forming part of Letters Patent No. 446,413, dated February17, 18.91.

Application filed May 27, 1890. Serial No. 353,350. (No model.)

To all whom it may concern:

Be it known that l, JAMES BAKER, a citizen of the United States,residing at St. Louis, State of Missouri, have invented new and usefulImprovements in Cooking and Heating Stoves; and I do hereby declare thefollowing to be a full, clear, and exact. description of said invention,reference being had tothe accompanying drawing, and to the letters orfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to that class of stoves for both cooking andheating, and in which a hydrocarbon oil or gas of any kind is employedto generate the heat.

My invention consists in a novel construction of double-Walled chamber,in which the articles to be cooked or heated are placed, having aportion of the escape-flue also provided With double walls forming anair-space with openings in each wall of the tine provided with aregister, and with openings in the outer wall near the lower end,whereby the deleterious or objectionable fumes may be directed andcarried out through the tine, and also the air entering the air-space,or said air heated in the space and directed into the apartment.

My invention further consists in certain novel features in theconstruction and arrangement of parts, all as hereinafter explained.

In the accompanying drawing the figure represents a front elevation ofmy improved cooker and heater, with the upper portion or doublewalledchamber in section, with an ordinary form of hydrocarbon-burner forgenern ating the heat.

The main body A may be ot' any desired form, and may consist of a lowercompartment B, with a single wall, having a burner B located therein andadapted to be closed by doors B. Arranged above the compartment B is asecond compartment O, having double walls C' C, with an inclined topalso formed with double walls to form an airspace between them. Theinner portion of the compartment C communicates with an outlet iiue orchimney D,-which can be connected with the iiue of a honse in the nsualmanner. The outer wall C extends up in cylindrical forni for a shortdistance, surrounding the chimney D, i`orming a continuation of theairspace. The outer Wall and flue or chimney are provided with a seriesof openings D D', respectively, those in the outer wall being locatednear the top of the cylindrical extension, while those in the flue orchimney are located near the point of junction of the same with thecompartment. Surrounding the iiue is a cylindrical register-plate E,withits upper edge extending up beyond th e top of the wall O, and havingsecured thereto a handle E for moving the register to open or close theopenings D in the chimney. A similar .register-plate G is arrangedaround the cylindrical extension, extending np slightly be ond the topthereof, and which is provit ed with an inwardly-projecting iiange Gr',

with its inner edge to abut against the register-plate E to close theannular opening between the two registers, and by means of whichregister-plate to open or close the openings D in the cylindricalextension ot' the wall O. A damper II is arranged in the flue 'at asuitable point therein, for a purpose hereinafter explained. The outerwall O, near the lower part of the airspace, is provided with a seriesof openings If for admitting air to the space.

The burners, as shown in the present instance, are of the approved formfor burning hydrocarbon oil, and are located at such point as to bringthe flame on a line With the lower edge of the air-space to produce thebest results, and the compartment is closed by suitable doors. (Shown bydotted lines.)

The operation of the cooker and heater is as follows: The burner beingignited, if it is desired to both heat and cook, the openings in thechimney communicating with the airspace are closed and those in thecylindrical extension are opened, and as a consequence all the offensiveodors willbe carried out of the chimney and the air entering theperforations at the lower edge of the compartment will pass up throughthe airspace and be heated and thence pass into the room, as shown byarrows l. IVhen, however, it is only desired to cook and to create astrong draft to carry oft the offensive odors arising from the articlesbeing cooked, the openings leading from the air-space into the chimneyare opened and those leading from the space into the room IOO closed.Then the air Will pass quickly through the air-space and out into thechimney, as shown by arrows 2, tending to keep the outer wall cool andprevent the heating of the apartment. When it is desired to increase theheat of the apartment, or when the burners are used for boiling Water,or closed Vessels are being used, or where no offensive odors arise, theopenings leading from the space into the chimney may be closed and thoseinto the apartment opened and the damperv in the flue closed, which willretain the heat in the compartment and cause the inner Walls to becomevery hot and consequently cause the air passing through the space to beheated to high temperature, as will be readily understood.

Having now described my invention, I claiml. In a heating and cookingstove, a doublewalled chamber in which the articles to be cooked orheated are adapted to be placed to form an air-space between the walls,an escape-flue leading therefrom having au airspace surrounding the sameand. forming a continuation of the main air-space opening near thebottom of the chamber, and register-openings in the escape-due and theouter Wall surrounding the same, substantially as described, whereby theair from the space may be directed eitherinto the chimney or to theapartment, as set forth.

2. In a heating and cooking stove, a double- Walled chamber forming anair-space, a iiue leading from the chamber surrounded by an air-spaceforming a continuation of the airspace surroundiug the chamber,registeropenings in the flue and iu the surrounding wall thereof, adamper located in the iue above the openings, and openings connectingwith the air-space surrounding the chamber located near the lower edgethereof, substantially as and for the purpose set forth.

In testimony whereof I afx my signature in the presence of twosubscribing witnesses.

J AMES BAKER.
